java.awt.image.BufferedImage类转com.itextpdf.text.Image类

可以使用以下代码将java.awt.image.BufferedImage类转换为com.itextpdf.text.Image类：

import java.awt.image.BufferedImage;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import javax.imageio.ImageIO;
import com.itextpdf.text.BadElementException;
import com.itextpdf.text.Image;
import com.itextpdf.text.pdf.codec.PngImage;

public static Image convert(BufferedImage bufferedImage) throws BadElementException, IOException {
    ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
    ImageIO.write(bufferedImage, "png", byteArrayOutputStream);
    byteArrayOutputStream.flush();
    byte[] imageBytes = byteArrayOutputStream.toByteArray();
    byteArrayOutputStream.close();
    return PngImage.getImage(imageBytes);
}

使用方法：

BufferedImage bufferedImage = ...
Image image = convert(bufferedImage);
